Fixed Inductors – CDRH125-820MC Application Field and Working Principle

Fixed inductors are highly versatile electrical components used in a myriad of industrial, commercial, and residential applications. The CDRH125-820MC Fixed Inductors are a particular type of fixed inductors with an application field spanning various electronics, ranging from power supply, power supply resonator, switching power supplies, AC/DC converters, inverters, and even consumer electronics. The CDRH125-820MC\'s especially notable for its low temperature coefficient, low residual inductance, and low resistance value.

Application Field of CDRH125-820MC Fixed Inductors

As a fixed inductor, the CDRH125-820MC is mostly used to filter or buffer electrical signals and components from one another. More specifically, they can be used as permanent inductors, bandpass filters, and resonance circuits.In terms of its electrical characteristics, the CDRH125-820MC stands apart from other fixed inductors. This particular type of inductor is notable for its low temperature coefficient, which means that its inductance value remains highly stable throughout changes in temperature. When used as a resonator, the CDRH125-820MC is also quite noteworthy for its low resonance frequency and low residual inductance, both of which ensure more reliable measurements. Additionally, the CDRH125-820MC also has a very low resistance value, and its small size saves a lot of space on a circuit board. The small size also helps reduce radio frequency interference from component-to-component.

Working Principle of CDRH125-820MC Fixed Inductors

The working principle of the CDRH125-820MC fixed inductors is based on Faraday\'s law of induction, which states that a changing magnetic field produces an electric field. This principle also explains why fixed inductors are used for filter applications.Whenever an electrical current passes through a wire, it creates a magnetic field around the wire. If the current is changing, then the magnetic field will change too. When two coils are placed side-by-side, they are affected by each other\'s magnetic field, which induces a small voltage in the other coil. This phenomenon is called mutual inductance.Fixed inductors use this mutual inductance principle to filter out undesirable signals, such as noise or interference. The CDRH125-820MC fixed inductors have two coils that are wound in opposite directions and then connected in series. This configuration cancels out undesired frequencies and therefore blocks them from reaching other components.

Conclusion

The CDRH125-820MC Fixed Inductors are a type of fixed inductor application specifically designed for power supply, power supply resonator, switching power supply, AC/DC converters, inverters, and consumer electronics applications. Its small size and low temperature coefficient, low residual inductance, and low resistance value make it the ideal choice for applications where power efficient performance is required. Furthermore, this type of fixed inductor uses the principle of mutual inductance to effectively filter out undesirable signals, allowing your circuitry to maintain its integrity.
